In mammals, environmental sounds stimulate the auditory receptor, the cochlea, via
vibrations of the stapes, the innermost of the middle ear ossicles. These vibrations produce …

Most sounds of interest consist of complex, time-dependent admixtures of tones of diverse
frequencies and variable amplitudes. To detect and process these signals, the ear employs …

Some published cochlear filterbanks are nonlinear but are fitted to animal basilar membrane
(BM) responses. Others, like the gammatone, are based on human psychophysical data, but …

This paper presents a computational model to simulate normal and impaired auditory-nerve
(AN) fiber responses in cats. The model responses match physiological data over a wider …

In the normal mammalian ear, sound vibrates the eardrum, causing the tiny bones of the
middle ear to vibrate, transferring the vibration to the inner ear fluids. The vibration …

This article provides a review of recent developments in our understanding of how cochlear
nonlinearity affects sound perception and how a loss of the nonlinearity associated with …

Mammalian hearing sensitivity and frequency selectivity depend on a mechanical
amplification process mediated by outer hair cells (OHCs). OHCs are situated within the …

Sound-evoked vibrations transmitted into the mammalian cochlea produce traveling waves
that provide the mechanical tuning necessary for spectral decomposition of sound. These …

This study examines auditory brainstem responses (ABR) elicited by rising frequency chirps.
Two chirp stimuli were developed and designed such as to compensate for cochlear travel …

To enhance weak sounds while compressing the dynamic intensity range, auditory sensory
cells amplify sound-induced vibrations in a nonlinear, intensity-dependent manner. In the …
